OBJECTIVETo evaluate the clinical efficiency of selective cyclo-oxygenase-2 (COX-2) inhibitor compared to traditional nonselective NSAIDs for the prevention of heterotopic ossification (HO) after total hip arthroplasty (THA).
METHODSBy searching Medline, Embase, CENTRAL (Cochrane Central Register of Controlled Trials) and Science Citation Index et al, only randomised controlled studies of selective COX-2 inhibitors VS nonselective COX-1 and COX-2 inhibitors for the prevention of HO after THA were included. The quality assessment of included studies was evaluated according to the standard of the Cochrane Collaboration, and the data were analysised by statistic software Stata 10.0. The HO incidence of both groups in different degrees was compared.
RESULTSFour eligible randomised controlled trials of totally 808 patients were included. Meta-analysis results showed that no statistically significant difference was found in overall incidence of HO (RR = 1.08, 95% CI: 0.71-1.64,P = 0.73), incidence of moderate severe HO (Brooker II and III) (RR = 0.83, 95% CI: 0.48-1.42, P = 0.49) and any grade of Brooker classification between two groups. In all included studies, 16 patients receiving nonselective COX inhibitor (4.4%) discontinued treatment because of gastrointestinal toxicity,whereas 10 patients in the selective COX-2 inhibitor group (2.7%) discontinued for gastrointestinal side effects.
CONCLUSIONThe selective COX-2 inhibitors are as equally effective as nonselective NSAIDs for the prevention of HO after THA. Considering the side effects of nonselective NSAIDs, selective COX-2 inhibitors were recommend for the prevention of HO after THA.

OBJECTIVETo observe clinical efficacy of Huazhuo Jiedu Recipe (HJR) on chronic atrophic gastritic precancerosis (CAGP), and its effect on contents of lactic acid, total acid, free acid, and nitrite in the gastric juice, as well as tumor markers in gastric juice and blood.
METHODSTwo hundred and twenty-nine patients with CAGP were randomly assigned to two groups, the 119 patients in the treated group orally took HJR and the 110 patients in the control group orally took Weifuchun Tablet. The therapeutic course for all was three months, two courses in total. The therapeutic efficacy, changes of gastric acid contents before and after treatment were observed, and the tumor markers in the gastric juice and blood were detected using electrochemical luminescence immunoassay.
RESULTSThe pathological effective rate was 83.2% (99/119) in the treated group and 60.9% (67/110) in the control group, showing significant difference between the two groups (P <0.05). The total acids and free acids in the gastric juice were significantly improved, contents of lactic acid and nitrite were significantly lowered in the two groups. Both contents of carcinoembryonic antigen (CEA), carbohydrate antigen19-9 (CA19-9), carbohydrate antigen72-4 (CA72-4), and carbohydrate antigen125 (CA125) in the gastric juice and serum were significantly lowered after treatment in the treated group (P<0.05). Compared with the normal control group, the therapeutic effect was more obvious in the treated group (P<0.05).
CONCLUSIONSHJR could stimulate the gastric membranous secretion, enhance contents of total acids and free acids. It could prevent the further progress of CAGP by decreasing contents of lactic acid and nitrite in the gastric juice, and lowering contents of CEA, CA19-9, CA72-4, and CA125 in the gastric juice and serum.

ObjectiveTo investigate the histological features as well as the factors influencing liver disease progression in Chinese patients with chronic hepatitis C (CHC). MethodsA total of 102 CHC patients who underwent percutaneous liver biopsy between August 2007 and May 2010 were recruited. Age, gender, body mass index (BMI) and transmission route of recruited patients were recorded. Serum levels of alanine transaminase (ALT) and aspartate transaminase (AST), HCV genotypes, HCV viral load and liver histological changes were detected. Statistical analysis was done by t test and Logistic regression. ResultsThe serum levels of ALT and AST in CHC patients with histological activity index (HAI) ≥4 were much higher, while platelet (PLT) counts were lower than those with HAI <4(t=2.209, 2. 298 and 2. 565, respectively; all P<0.05). Likewise, in patients with F≥3, the serum levels of ALT and AST as well as the mean age and the duration of infection were significantly elevated compared with F < 3 group ( t = 3.497, 2. 758, 2. 340 and 2. 570,respectively; all P<0. 05), while PLT counts were much lower (t = 2. 761, P=0. 007). The unvariate predictors for HAI≥4 were female, ALT>1 × upper limits of normal (ULN), AST level,F≥3, HCV RNA≥6 lgIU/mL and PLT counts. By mutivariate analysis, the Ishak stage score was the only independent predictor for HAI≥4 (OR 3.098, 95%CI 1.884-5. 092; P<0.01). Finally,the univariate predictors for F≥3 were age, BMI≥24 kg/m2 , ALT>1 × ULN, AST level, HAI≥4,PLT counts and duration of infection≥ 15 years. Multivariate analysis revealed that age (OR 1. 074,95%CI 1.006-1. 146; P=0.033), ALT level (OR 1. 035, 95%CI 1.015-1.055; P<0.01), ASTlevel (OR 0. 969, 95%CI 0. 948-0. 990; P=0. 005), the duration of infection ≥15 years (OR 37. 215, 95%CI 5. 816-238. 127; P<0.01) and HAI≥4 (OR 1. 939, 95%CI 1. 426-2. 636; P<0.01) were independent predictors for F≥ 3. ConclusionAge, ALT level, AST level, duration of infection≥15 years, HAI≥4 are independent predictors for liver fibrosis.

Objective To observe the influence of coal burning fluorosis on learning and memory ability in rats and reveal its possible mechanisms. Methods Healthy 48 SD rats were divided into control, low-fluoride and high-fluoride group. All rats in fluoride exposed groups were fed with the eom polluted by drying processes with burning coal containing high level of fluoride obtained from the endemic fluorosis area to produce the animal model of fluorosis. The experiment period were 3,6 mouths, respectively. The ability of leaning and memory was measured by Morris test and cholinesterase activity detected by photometric method at 3 or 6 month after experiment, respectively. Results Fluoride contents signifieantlly influenced the escape latency, the numbers of crossing the platforms and the time of staying the platforms(the value of F was 29.29,6.47,6.50, respectively, P<0.01).In addition, the numbers of crossing the platforms and the time of staying the platforms were influenced by the exposed time(the value of F was 16.11,45.59, P<0.01). Furthermore, the fluoride contents and the exposed time had an interaction between the numbers of crossing the platforms and the time of staying the platforms (the value of F was 4.67,5.68, P<0.05 or<0.01). Three months after the experiment, the mean values of escape latency [(14.71± 4.85)s] of rats in highly fluoride exposed group were significantly prolonged as compared with controls [(9.28±4.22)s]; 6 month after the experiment, the mean values of escape latency[(12.42±8.03)s, (17.48± 8.05)s] of rats in both groups exposed to fluoride were significantly prolonged as compared to controls [(7.04± 3.29)s, P<0.05]. The decreased numbers of crossing the platforms[(1.62±0.87)number] and the declined time of staying the platforms[(16.70±5.02)s] were found in the rats exposed to high fluoride as compared to controls [(3.53±1.67 )number, (23.33±5.35)s, P<0.05]. The fluoride contents obviously influenced the activities of acetylcholinesterase and butylcolinesterase (the value of F was 12.83,13.27, P<0.01). On the other hand, the times of breeding also influnced the activities of butylcolinesterase (the value of F was 16.26, P<0.01). In 3 months of the experiment, the activities of butylcolinesterase [(0.55±0.12)kU/g] in low fluoride exposed group were significantly decreased in comparison with controls[(0.73±0.10)kU/g, P<0.05]. The activities of acetylcholinesterase[(0.62±0.42)kU/g] and butylcolioesterase[(0.58±0.10)kU/g] in high fluoride group were significantly decreased as compared to eontrois[(1.41±0.52), (0.73±0.10)kU/g, P<0.05]. The correlation analysis showed that there was a negative correlation between the cholinesterase and the escape latency(r=-0.68, P< 0.01), and a positive correlation between the cholinesterase and the time of staying the platforms(r=0.57, P< 0.01). Conclusions The ability of learning and memory in rats with coal buring fluorosis was decreased, which might be connected to the decreased activity of cholinesterase in a dose-effect correlation.

The study established an HPLC-MS/MS method for determining the concentrations of sodium cromoglycate in human plasma and evaluated the pharmacokinetics of nasal drops and nasal spray. A C18 column was used to separate sodium cromoglycate in plasma with a mobile phase of a mixture of ammonium-methanol (involves 50% acetonitrile) (15:85) at a flow rate of 0.4 mL x min(-1). Electronic spray ionization (ESI) and multiple-reaction monitoring (MRM) were used for the determination of sodium cromoglycate in human plasma. The linear range of the standard curve of sodium cromoglycate was from 0.3 to 20 ng x mL(-1), and the minimum concentration of detection was 0.3 ng x mL(-1). The extraction recovery was more than 94.1%, intra-day and inter-day RSD were less than 14.3%. After a single dose of sodium cromoglycate, the main pharmacokinetic parameters of nasal spray and nasal drops were as follows, T(1/2)(1.82 +/- 0.54) h, (1.59 +/- 0.52) h; Tmax (0.47 +/- 0.12) h, (0.44 +/- 0.15) h; Cmax, (9.79 +/- 4.66) ng x mL(-1), (10.88 +/- 4.05) ng x mL(-1); AUC(0-5 h)(11.52 +/- 3.46) ng x mL(-1) x h x h, (12.63 +/- 4.23) ng x mL(-1) x h, Fr(93.6 +/- 13.8)%. The method is sensitive, rapid and accurate. It is suitable for therapeutic drug monitoring and human pharmacokinetic study of sodium cromoglycate.
